For which of the following, Kjeldahl's method is not used for the estimation of nitrogen?
I. Aniline
II. Azobenzene
III. Nitrobenzene
IV. Pyridine
- A II, III, IV
- B II, III only
- C III, IV only
- D I, III, IV
Answer & Solution
Correct Answer
(A) II, III, IV
Step-by-step Solution
Detailed explanation
Key Idea The groups in which nitrogen contain double bond or present in heterocyclic ring can not be estimated by Kjeldahl's method. aniline does not contain double bond, it can be estimated by Kjeldahl's method. (II) Azobenzene contain \(-\mathrm{N}=\mathrm{N}-\) group, thus…
